Auras are the passive-buff system in Be a Fish Bait, the Roblox simulation by VoidDeckStudios where you play as the bait instead of the angler. Each Aura grants a fixed bonus to things like Aquarium Income, Mutation Luck, Training Power, or Boss Fish skill checks, so the one you land on directly shapes how fast your run grows. Ten Auras are currently in rotation, split across six rarity bands.
Quick answer: Open the Index menu, spin the Aura Gacha, and each spin gives one random Aura weighted by its drop rate. Voidspore is the rarest at 0.5%; Fire is the most common at 32%.
How Auras are pulled
You unlock Auras through the Aura Gacha, which sits inside the Index menu. Every spin hands you a single Aura at random, and the odds are weighted by that Aura’s roll chance. Some Auras stack cash through Aquarium Income, others improve your odds of landing mutated fish, help you clear Boss Fish, or speed up leveling. Because no two Auras do the same job, rerolling toward the one that fits your goal matters more than the rarity alone.
Every Aura, rarity, and roll chance
The table below lists all ten Auras, their rarity, the chance to pull each one, and the exact buffs they apply.
| Aura | Rarity | Roll Chance | Buffs |
|---|---|---|---|
| Fire | Common | 32% | +3% Aquarium Income |
| Yinyang | Uncommon | 17.5% | +10 Mutation Luck |
| Lines | Uncommon | 17.5% | +4% Bait Hop Distance |
| Heart | Rare | 10% | -8% Shop and Upgrade Prices |
| Frost Petal | Rare | 10% | +15% Bigger Boss Fish Skill Check Circles, +25% Boss Fish Skill Check Progress |
| Rainbow Fire | Epic | 5% | +15% Aquarium Income, +10% Mutation Luck |
| Snow | Epic | 5% | +10% Bonus Luck, +10% Training Power |
| Demon | Legendary | 1.25% | +15% Bonus Luck, +15% Training Power, +20% Champion Mutation Chance |
| Angel | Legendary | 1.25% | +15% Aquarium Income, +15% Mutation Luck, +5% Bait Hop Distance |
| Voidspore | Mythic | 0.5% | +20% Aquarium Income, +15% Mutation Luck, +20% Training Power, +10% Weather Mutation Luck |
Which Aura fits your goal
Pick the Aura that matches what you are trying to push. If you are chasing raw cash, Voidspore, Angel, and Rainbow Fire all carry Aquarium Income bonuses, with Voidspore’s +20% being the highest single value. For landing mutated fish, Yinyang, Rainbow Fire, Angel, and Voidspore all raise Mutation Luck. Boss Fish grinders benefit most from Frost Petal, which enlarges skill-check circles and speeds up progress. If leveling is the priority, Snow, Demon, and Voidspore all add Training Power.
Note: Demon is the only Aura that raises Champion Mutation Chance, and Voidspore is the only one with Weather Mutation Luck, so those two are worth targeting if either mechanic is your focus.
How to get Aura Rerolls
Rerolls let you spin again for a shot at a better Aura. There are three ways to build up a supply.
- Redeem the latest game codes, which can include Aura Rerolls among their rewards.
- Claim Daily Rewards, which may hand out Aura Rerolls alongside Wheel Spins and other items.
- Buy Aura Rerolls with Robux through the in-game Store or directly from the Aura Gacha.
You can launch the experience directly to start spinning and collecting rerolls.
Because every Aura is a permanent passive bonus once equipped, the practical play is to keep a stock of rerolls and spin toward the buff that supports your current bottleneck, whether that is cash flow, mutation odds, Boss Fish clears, or faster training. Voidspore covers four of those at once, which is why its 0.5% pull rate makes it the standout target for players willing to grind rerolls.
